Insights
Auditory Steady-State Response (ASSR) effectively assesses hearing thresholds in infants and children. Recent studies show improved ability to differentiate mild hearing loss from normal hearing using this electrophysiological method.
Area of Science:
- Audiology
- Pediatric Medicine
- Neuroscience
Background:
- Hearing deficits in children can significantly impede development.
- Early and accurate hearing assessment is crucial for timely intervention.
- Electrophysiological methods offer objective measures for hearing evaluation in pediatric populations.
Purpose of the Study:
- To review the literature on the effectiveness of Auditory Steady-State Response (ASSR) for assessing hearing thresholds in infants and children.
- To evaluate ASSR's capability in distinguishing mild hearing loss from normal hearing.
- To identify areas for further research in pediatric audiology.
Main Methods:
- A systematic literature review was conducted using PubMed, Web of Science, and Scopus databases.
- Searches covered articles published between 2014 and 2024.
- Inclusion criteria were applied to select relevant studies on ASSR in pediatric populations.
Main Results:
- The review identified 16 studies meeting the inclusion criteria from an initial 1226 articles.
- Auditory Steady-State Response (ASSR) was confirmed as a reliable diagnostic tool for assessing hearing in babies, infants, and children.
- More recent research demonstrates enhanced accuracy in distinguishing mild hearing loss from normal hearing thresholds.
Conclusions:
- ASSR is a valuable and reliable electrophysiological technique for pediatric hearing assessment.
- The diagnostic precision of ASSR, particularly for mild hearing loss, has improved in recent years.
- Further investigation is needed regarding the efficacy of bone-conducted stimuli with ASSR in children.
Abstract:
The assessment of hearing in children is important, as hearing deficits can impair child development. The Auditory Steady-State Response (ASSR) is an electrophysiological technique that is able to simultaneously evaluate both ears at four frequencies, making it advantageous for testing children where the test time needs to be as short as possible. The objective of this work was to perform a literature review on the effectiveness of ASSR to gauge hearing thresholds in babies, infants, and children, examining its ability to distinguish mild hearing loss from normal cases. This review used PubMed, Web of Science, and Scopus databases from 2014 to 2024. A total of 1226 articles were identified, although only 16 met the previously established inclusion criteria. It was found that ASSR is a reliable diagnostic tool for babies, infants, and children. Recent work appears better able to distinguish mild hearing loss from normal hearing. One unresolved aspect that needs additional attention is the effectiveness of using bone-conducted stimuli.
